Specification of Letters Patent.

Patented Oct. 4:, 1921.

Application filed .Tune 11, 1921. Serial No. 476,925.

To all whom it may concern Be it known that I, CHARLES RooHoN, a citizen of the United States, residing at Fall River, in the county of Bristol, State of Massachusetts,have invented certain new and useful Improvements in Window-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window screens such as that shown in United States Letters Patent No. 1,168,558, granted to me 18th January 1916, and it has for its object to provide such improvements as will adapt the screen to windows of different widths, and will render the fly exits at times inoperative.

In the drawings:

Figure 1 is a perspective view of a screen embodying the present invention, portions of the wire fabric being broken away.

Fig. 2 is a vertical section on the line 2-2 of Fig. 1.

Fig. 3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a top plan view of the top rail, showing the reduced end portions as well as the rabbet in which the slide bar operates.

Referring now to the drawing the window screen includes a body member, similar to that shown in Letters Patent above referred to, together with slidably connected wings that permit of adjustment of the width of the structure to suit different windows and to facilitate application to a window.

The body member includes side bars 1 and 2 together with top and bottom rails 3 and 4, respectively. The wings are shown at 5 and 6 and are similarly constructed as well as connected to the body member.

The side bars 1 and 2 are each rabbeted on one face as shown at 7, with a resultant longitudinal flange 8 at its outer edge, for a purpose to be presently explained and each bar has its same face further rabbeted at each end as shown at '9, these last named rabbets extending transversely with resultandbottom rails areincreased in thickness at their end portions as shown at 25, comes onding to the depths of these last named ra bets, in which they are received in spaced relation to the shoulders 10. The inner longitudinal edges of the rails 3 and 4 are rabbeted at their inner corners as shown at 11 to form L- shaped guide grooves in connection with the adjacent side bars and these grooves receive the L-shaped guide strips 1 1 that are secured transversely of the inner faces of the wings 5 and 6 and project materially beyond the inner longitudinal edges of said wings. It will be noted that the side wings are dis posed directly against the top and bottom rails 3 and 4, along which they are adapted to slide, their outward movement being-limited by the strips 12 and 13 attached to their inner faces in positionsto engage the flanges 8 of the side rails, while their inward movement is limited by contact of the guide strips 14 with the inner end walls of the channels 14 that extend longitudinally of the top and bottom rails 3 and 4 in which they slide.

This structure is found in practice to be extremely durable, while interfering in nowise with the operation of the fly exits 16 that are formed in the outer face of the top rail 3 and are bridged by the wire fabric 17. These exit openings communicate with rabbet 17 that is formed in the upper outer corner of the top rail 3 and extending from one side bar to the other. In this rabbet is also disposed a slide bar 19 which is cut away at intervals as shown at 20 and through a slot 21 in the bottom of the rabbet is passed a handle 22 that is engaged with the slide plate for manipulating it to cover and uncover the exit openings, as will be understood, the handle being at the inner face of the screen fabric.

What is claimed is:

1. In a window screen the combination with a frame including side bars having their end portions rabbeted with resultant transverse shoulders and top and bottom rails disposed in corresponding rabbets in spaced relation to the shoulders thereof, the corners of the top and bottom bars opposite the shoulders being longitudinally rabbeted throughout the widths of the corresponding side bars and then channeled beyond the corresponding side bars, of wings each having L-shaped guide strips disposed transversely of its ends and slidably engaged in corresponding rabbets and channels of the rails and between the rails and the shoulders of the bars.

2. The combination with a window screen frame and its fabric covering, the frame having its upper corner rabbeted at the side next the fabric and having egress openings formed therethrough between it and the fabric, of a plate slidably mounted in the rabbet and having-cutaway portions registerable attimes with the egress openings 5 and an actuating handle carried by the plate, the rail having a slot through which the handle depends.

In tes timony whereof, i afiix my signature, in the presence of two Witnesses.
